Abstract
An ink jet printing apparatus that includes a springbacked fluid interconnect seal that provides a seal between an ink handling component and an ink pipe that is attached to the ink handling component. The spring-backed fluid interconnection seal more particularly includes a generally conically tapered resilient seal, and a pre-loaded spring configured to axially extend or tension the seal. An exemplary embodiment of the invention includes a groove in the sealing face which allows the use of a liquid sealant. The groove holds the sealant in place through capillary forces, and also by virtue of trough-like shape protects the sealant from being wiped away through mechanical member.
